In this thesis, based on this kind of application, we made theoretical analysis and engineering practice on high - precision lfmcw and its signal processing millimeter wave broadband lfmcw radar has quite high theoretical range - precision and distance resolution, however, for the real radar system, the nonideal parameter of its transmitting signal, such as power fluctuation and the nonlinearity in frequency sweep, will result in the decreasing of the practical rang - precision and the distance resolution of radar
本文基於這一應用對高精度lfmcw測距雷達及其信號處理進行了理論分析和工程實踐。毫米波寬帶lfmcw雷達具有很高的理論測距精度和距離分辨力，但對于實際的雷達系統，其發射信號的非理想參數-掃頻功率起伏和掃頻非線性，將使得雷達的實際測距精度和距離分辨力下降。 -
